Main point is I agree with GasGod, it needs SOMETHING more to not be Yet Another Survivors Like. Even if you're not an ideaguy, try to think of something to set it apart. Free GimmickTM: what if the different weapons were different items of clothinng you would see on the protagonist: really lean into the anime coomer market.
1. Very nice pixel art, though I some nitpicks. First, I feel the protagonist is too detailed compared to the enemies, almost giving the impression of mixels. Maybe you could make her a bit more simplified? Second, I think the background is a bit too noisy. The screenshots look significantly worse than the actual gameplay IMO, and I think that's part of it. The enemies are the highlight for me.
2. Mouse controls are really weird, seems like it's centered a couple of inches to the right of the protag. IMO just scrap mouse controls, what kind of psychopath wants to control a survivorslike with their mouse?
